Python Exception Handling

Syntax Errors

• Syntax errors or parser errors are errors what occur due to mistakes in the syntax of the code.
• At any point in the running state of the code if an Error occurs the program should not try to recover from it but rather exit gracefully

Logical Errors (Exceptions)

• Exceptions are raised when an external event occurs which in some way changes the normal flow of the program.
• A user defined exception can be created using the raise keyword

amount = 2000
try:
    if amount < 2999:
        raise ValueError("Please add money in your Account")
    else:
        print("You are eligible to purchase DSA Self Paced course")
except ValueError as e:
        print(str(e))

The try except block can take an optional
The finally block can be used to perform clean up operators that must be performed under all conditions
